Sex in Heraldry

Foul Fowl

According to Nicholas Upton (De studio militari, 15th c., published
1654), the earl of Salisbury once gave arms to a valiant soldier which
consisted of 3 partridges; which Upton explained as an allusion to the
man's homosexuality, since, according to medieval bestiaries, the partridge
displayed "aberrant" behavior. (Cited in Dennys, The Heraldic
Imagination).

Kinky!

Woodward's Treatise of Heraldry cites the coat of arms of the
Pomeranian family of Pirch, which also appears in Rietstap and is illustrated
in Rolland. Impaling the coat of Pirch ( Azure a perch per pale argent,
canting arms) is the following: Gules on a terrasse vert a woman nude,
between her legs a fox running from dexter to sinister, holding hay in
its mouth, the woman holding the tail of the fox and rubbing her body with
it.

Parts (missing or otherwise)

Human

Interesting example of canting arms: the family of Coglione, in Naples,
bore per fess argent and gules, three pairs of testicles counterchanged.
One Bartolomeo Coglione, a soldier who distinguished himself in the service
of René d'Anjou, king of Naples, was allowed to quarter his arms
with those of his king (France ancient with a bordure gules).

Animal

If the sex of the animal is of a different tincture, the animal is said
to be vilené (pizzled in English blazon). If the sex
is missing, the animal is éviré. I don't think you need to
blason the fact that the horse is anatomically correct if the sex is not
of a different tincture (lions ought to be correct in the first place).

From tsulyok@kn.pacbell.com (Tom Sulyok):
A long time ago I read in a book of "hi(y)sto(e)rical curiosities"
that Ferdinand I, King of Hungary, (1526-15??) ennobled a Hungarian soldier
whose original occupation had been "gelder". The arms given him
contained among others, an anatomically correct horse (or maybe only the
pertinent part[s] coupé proper?) and a small knife.
